Explanation:
Warm shades and subtle colours come to the sky in the fading sunlight
after shadowrise on this little planet.
Of course the little planet is planet
Earth, and this
nadir-to-zenith,
around-the-horizon mosaic
maps the view from a small airfield near the town of
Intendente Alvear, La Pampa province, Argentina.
Just above the western horizon (top) the sky shines with the warm
colours
of sunset.
The slate blue
shadow of Earth
itself extending through the atmosphere
can be seen rising as it hugs the eastern horizon (bottom).
Wrapped closely above the narrow projection of Earth's shadow is
the gentle glow of reddened, backscattered sunlight called the
antitwilight
arch or the Belt of Venus.
